What ever happened to CARNY_RIDE EXE?

When I used Norton AV the scanner used to get hung up looking for this malware (rootkit/virus). Eventually Symantec admitted that there was a bug in Norton that made it get hung up on quick scans looking for this 'faux virus'. I got Norton with my ISP originally, I don't use it any more.

I never actually found out what CARNY_RIDE was, although worrying about it made me download & test several anti-malware apps until I settled on SUPERAntiSpyware & SpywareBlaster.
